Description
Technical field
The utility model relates to a kind of milling cutter, especially a kind of groove is integrally formed knife.
Background technique
Need to process groove on handset shell, former milling cutter is horizontal positioned, and blade is set to the side of knife bar, then stretches
Enter the groove of processing non-regular shape in mobile phone shell body, above-mentioned processing method difficulty of processing is big, thus the applicant devises one
Kind integrated molding knife can be by the way of vertically processing to the three surface processing of groove, to reduce difficulty of processing.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of groove integrated molding knife.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of groove integrated molding knife, it is characterised in that: knife bar, knife neck, cutterhead including sequence setting, the cutterhead
Annular is evenly equipped with equipped with several with the integrally formed blade part of cutterhead on side, the blade part include arc rake face and
Left side major first flank, bottom surface major first flank, right side major first flank, the second flank of left side, the second flank of bottom surface, the right side
The second flank of side, the rake face intersect composition left side cutting edge with left side major first flank, the rake face and bottom surface the
The intersection of one flank constitutes bottom surface cutting edge, and the rake face intersects composition right side cutting edge with right side major first flank, described
Left side cutting edge, bottom surface cutting edge, right side cutting edge continuously intersect, and the side of the rake face and cutterhead constitutes chip space, institute
The shape for stating left side cutting edge and bottom surface cutting edge is curved line, and the shape of the right side cutting edge is straight line, and left side is cut
Sword, bottom surface cutting edge, right side cutting edge is cut to be smoothly connected.
One edge of the left side major first flank and bottom surface major first flank is smoothly connected, the bottom surface major first flank
Another side along being smoothly connected with right side major first flank.
Second flank of left side intersects with left side major first flank and the second flank of bottom surface；The bottom surface second
Flank also intersects with bottom surface major first flank and the second flank of right side；Second flank of right side also with right side first
Flank intersection.
The beneficial effects of the utility model are: the utility model includes the knife bar of sequence setting, knife neck, cutterhead, the knife
Annular is evenly equipped with equipped with several and integrally formed blade part of cutterhead on the side of disk, and the blade part includes the preceding knife of arc
Knife behind face and left side major first flank, bottom surface major first flank, right side major first flank, the second flank of left side, bottom surface second
Face, the second flank of right side, the rake face intersect composition left side cutting edge, the rake face and bottom with left side major first flank
Major first flank intersection in face constitutes bottom surface cutting edge, and the rake face intersects composition right side cutting edge with right side major first flank,
The left side cutting edge, bottom surface cutting edge, right side cutting edge continuously intersect, and the side of the rake face and cutterhead constitutes chip removal
Slot, by above structure, it is irregular annular groove that this cutter can process cross-sectional shape in mobile phone shell vertically, and
And can be to the three surface processing of groove, while the structure of chip space can guarantee that solid capacity is big, and blade part intensity Gao Qiwei
It installs convenient for being processed in mobile phone shell, to reduce difficulty of processing.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the three-dimensional view of the utility model；
Fig. 2 is partial enlarged view.
Specific embodiment
Referring to Fig.1, Fig. 2, the utility model discloses a kind of grooves to be integrally formed knife, knife bar 1, knife including sequence setting
Neck 2, cutterhead 3, annular is evenly equipped with equipped with several with the integrally formed blade part of cutterhead 3, the blade on the side of the cutterhead 3
Portion includes rake face 4 and left side major first flank 5, bottom surface major first flank 6, right side major first flank 7, the left side of arc
Two flanks 8, the second flank of bottom surface 9, the second flank of right side 10, the rake face 4 intersect structure with left side major first flank 5
At left side cutting edge 11, the rake face 4 intersects with bottom surface major first flank 6 constitutes bottom surface cutting edge 12, the rake face 4 with
The intersection of right side major first flank 7 constitutes right side cutting edge 13, the left side cutting edge 11, bottom surface cutting edge 12, right side cutting edge
The side of 13 continuous intersections, the rake face 4 and cutterhead 3 constitutes chip space, the left side cutting edge 11 and bottom surface cutting edge 12
Shape be curved line, the shape of the right side cutting edge 13 is straight line, and left side cutting edge 11, bottom surface cutting edge 12, right
The V-shaped similar to a round bottom of the cross-sectional profiles for the groove body that side cutting edge 13 is smoothly connected, thus finally processes, knife
The structure of disk 3 and knife neck 2 is convenient for avoiding the interference with processed component, to be conducive to vertical milling.
As shown, an edge of the left side major first flank 5 and bottom surface major first flank 6 is smoothly connected, the bottom
The another side edge of face major first flank 6 is smoothly connected with right side major first flank 7.Second flank of left side 8 and left side the
